off automatically when engine stop is active when the vehicle is stationary:
The driver seat belt has been unfastened.
No pedals are depressed.
The driver door is opened.
If the ignition is deactivated automatically while the dipped beam headlights are switched on,
the side lights remain switched on and lit for approximately 30 minutes.
The side lights can be switched off manually or will go off when the vehicle is locked.
Engine restart function
If no valid vehicle key is detected in the vehicle interior once the engine has been switched off, the
engine can be restarted within approximately five seconds. A corresponding message appears on the
instrument cluster display.
After this time, the engine cannot be re-started without a valid vehicle key in the vehicle interior.
WARNING
Unintentional vehicle movements can cause serious injury.
Do not depress the brake or clutch pedal when the ignition is switched on as the engine will start
immediately.
WARNING
Improper or unsupervised use of the vehicle keys can cause accidents or serious injuries.
Always take all vehicle keys with you every time you leave the vehicle. Children or unauthorised
persons could lock the vehicle, start the engine, switch on the ignition or operate electrical
equipment such as the electric windows.
Before leaving the vehicle, always switch off the ignition manually and observe any information
shown on the instrument cluster display.
Leaving the vehicle stationary for long periods with the ignition switched on can discharge the 12-
volt vehicle battery so that the engine can no longer be started.

A minimum engine temperature has been reached.
Vehicles with Climatronic: the temperature of the vehicle interior is within the preset
temperature range, and the humidity level is not too high.
The defrost function of the air conditioning system is not switched on.
The charge level of the 12-volt vehicle battery is sufficient.
The temperature of the 12-volt vehicle battery is not too low or too high.
The vehicle is not on a steep uphill or downhill gradient.
Vehicles with DSG dual clutch gearbox: the steering wheel is not turned too sharply.
The windscreen heating is not switched on.
Reverse gear is not engaged.
Park Assist is not active.
When the conditions for automatic engine switch-off are fulfilled only during a stationary phase, the
engine can also switch off subsequently, e.g. after switching off the defrost function.
Conditions for an automatic restart
The engine can start automatically under the following conditions:
If the temperature inside the vehicle substantially increases or decreases.
If the vehicle starts rolling.
If the electrical voltage of the 12-volt vehicle battery drops.
If the steering wheel is moved.
As a general rule, the engine always starts again automatically when required by the detected
situation and for the vehicle.
Conditions that require a manual engine start
The engine must be started manually in the following conditions:
If the driver door is opened.
If the bonnet is opened.

Also stow small objects safely.
If necessary, fold back the rear seat backrest and engage it securely.
If necessary, adjust the headlight range Headlights

WARNING
Objects that are not secured, or are secured incorrectly, can cause serious injuries in the event of a
sudden driving or braking manoeuvre or accident. This applies particularly if objects are struck by an
airbag when activated and then flung through the vehicle interior. Please observe the following rules
to reduce the risk of accidents:
Always stow all objects in the vehicle securely.
Small and light objects should also be secured.
Objects should be stowed in the vehicle interior in such a way that they can never enter the airbag
deployment zones while the vehicle is in motion.
Always keep stowage compartments closed while the vehicle is in motion.
Stowed objects must never cause passengers to assume an incorrect sitting position.
If an item is being stowed on a seat, this seat must not be used by any passengers.
Do not stow any hard, heavy or sharp objects loose in any of the vehicle's open stowage areas, on
the surface behind the rear seat backrest or on the dash panel.
Remove any hard, heavy or sharp objects from items of clothing and bags inside the vehicle and
stow them securely.
WARNING
Transporting heavy objects changes the vehicle's handling and increases the braking distance. Heavy
loads that are not properly stowed or secured in the vehicle can lead to a loss of vehicle control and
can cause serious injury.
